Mode of action

The product quickly penetrates the plant and accelerates the biosynthesis of ethylene in plant tissues. Ethylene is a plant hormone that regulates many physiological processes in the plant. For example, due to the accumulation of ethylene, the growth of the root system is stimulated and the growth of the stem is inhibited, which leads to shortening of the stem and thickening of the second and third internodes, straw walls, as well as an increase in the number of productive stems.
This feature of ethylene is important in preventing lodging of grain crops. Also, ethylene accelerates the formation and ripening of the crop.

Protective effect period

During vegetation or storage period after treatment.

Speed of action

7 to 10 days after treatment.
